EXPLOSION-PROOF ROTARY ENCODERS
Heidenhain Corp. has introduced an explosion-proof version of the ROD 420 rotary encoder. The rotary encoder with a housing diameter of 58 mm features an overall length of 83 mm and complies with the requirements of the directive 94/9 EG (ATAX 100a). The encoder is available with line counts of 250 to 5000.
The maximum surface temperature is 120°C. Before the housing attains the maximum permissible temperature, an additional temperature sensor triggers a warning signal to return the system to a safe operating condition.
